I know some impressive millennials who act like adults at age 18, 21 or occasionally 25. I know others who will never get there. If you know whether they act like adults, you can predict their politics. If you know their politics, you can predict how they will act.
Liberal snowflakes just want to crawl into a safe room with Play-Doh and never grow up. Young conservatives are ready to make the world a better place, get rich doing it, and raise children while they are at it.
Anytime this topic pops up I have to remind myself, a good deal of the military actually putting their lives on the line the past 15 years are likely Millenials.
